问题
I see people talking about the annoyance of Visual Studio automatically creating a namespace to correspond with project folders. Is there a way to turn this off in VS 2010, without resorting to modifying class templates?
回答1:
If you use Resharper, there is an attribute on the folder 'Namespace Provider'.
Even if you set it to false, Visual Studio will still add folder name as a namespace. However, Resharper fixes it with one click on the namespace.

Use Resharper. Turn off the "Namespace Provider" option and you should be good to go without modifying class templates.
